To all-whom it may concern: 5

Be it known that I, JOHN H; .TURooTT'E, a

subject oflthe King of Great Britain, residing at-Indiitn-Orchard, in the county of Hampden and State of Massachusetts, have in-. vented a new anduseful Spinning or Twist ing Apparatus, ofiwhich the following is a specification.

- My invention relates to improvements in apparatus, for ring+spinning frames or twisting machines, deslgned to guide 'the yarn or thread-as it passes to a yarn carrier or spindle andto put a dragon'sa-id yarn or thread, and said invention comprises in general a holder adaptedto be fastened to the recipro eating ring-rail of the machine, a revoluble' ring or guide of peculiar construction, a notched screw cap or' cover on said. holder, said guide being arranged and adapted to run freely in the holder and cap, and one or more cleaners mounted on said cap, all as hereinafter set forth-.. y

The objects of my invention are, first, to

produce a comparatively. light, simple and the draft created by the rapidly. revolvingspindle and bobbin to facilitate the rotation of the thread guide of'the apparatus and also to remove lint, dust and dirt from the apparatus and'from the yarn or thread in connection with which said apparatus is employed; fourth, toafford means for preventing any accumulation of dirt to collect between the vertical arms of said guide and the cap; fifth, to dispense with separators by making provisions for otherwise cleaning the yarn or thread as it whips out or balloons, whereby specks are removed from the same and hard places andbunches therein are smoothed out, the cleaners on the cap performingthese of fi ces, and sixth, to furnish an apparatus which not only possesses the advantages above enumerated, but as a whole is en-- tirely practical, efficient and satisfactory. I attain these objects by the means illustrated in the accompanying drawings, in which- Figure 1- is aside elevation of my apparatus mounted on a ring rail inoperative relation with a spindle and bobbin, the front cleaner being omitted; Fig. 2, a sectional view of the apparatus and rail, the guide standing" in a different position from that shown in the preceding view; Fig; 3, a top plan view of the apparatus alone, said guide aving still another different relation to the other parts, and, Fig. 4, a side elevation of the guide.

Similarfigures refer to similar parts throughout the several views.

In each of Figs. land 2 a portion of an ordinary rin -rail- I havin ano enin fl for the O b D spindleand bobbin is shown, and in the first of these views a spindle 3 together with a bobbin. 4 with yarn 5 thereon appear.

My apparatus comprises three major elements, namely, a base piece or holder 6, a

guide 7, and a cover or cap 8, inv addition to which are one or more cleaners 9, and other auxiliary and subsidiary parts and members, all of which I will now proceed to describe in detail.

The holder is in the form of an externally screw-threaded ring Which is'provided on the inside at the bottom with a ball-race 10 and has two or more laterally-extending cars 11 at the base. The ears ll'have slots-12 therein for screws 1'3 by means of which the holder 6 is securely fastened on the ring-rail 1.

These slotted ears enable the holder to be pro )erl'yadjusted on the ring-rail sothat sai holder will be concentric with the spin- -dle 3. A groove l4 maybe made in the out side of the holder to jointhe slot 12 in each ear 11 to receive the head of the correspondingvscrew 13 when the nature' of the adjustment requires. A set-nutvor lock-ring 1-5 for the capis placed on the threaded part of the.

holder. The cap 8- which is also in the form of a ring, has a depending externally screwthreaded' flange which fits the aforesaid threaded part of the holder. Four notches 16, more or less, are formed in the inner edge of the-capS, forthe'purpose presently to be explained. These notches may be rectangular orof any other suitable sh'ape, buteach should present a sharp'corner or'edge to the' "passmg guide members.

the. cap'isa ball-race 17. g

The guide 7 consists of-a'hollow shell hav- On the inside of" balls n the two races' s produced, after which; the lock-ring is screwed up right g h are ad justably mounted on top of the cap 8,

' 'portioned that the guide fits loosely within a ball-recess in the bottom and another in the top for balls 22-22 which travel in theballraces 10 and 17 when the guide revolves. Thus it will be seen that thg holder supports thelguidean'd the.'cap'keepssaid guide in place, it'beingunderstoodthat in assembling the guide is first placed in'the holder with the supports 20 resting on the balls .22 in the lower race and then the cap is placed on said liolderaround the arms 21 and screwed down until just the right amount of pressure on the.

Y r v 1 against the lower edge of the cap flange to preye rtthecap from becoming accldentally loosened'or displaced. The parts are so. protheholderaml the arms 2'] .lit loosely within the. cap,.'wl iile the passage through said guide is large enough to accommodate a full bobbilron the spindle. Each arm 21 resembles more or less closely a hook the eye 23 of which recelves the yarn or thread on its way to the bobbin, which yarn or thread may be slipped into the eye through the slot 24 in the edge of said arm that is behind in the direc tion'of rotation of the guide.

These eyes niay be reinforced with any suitable antifriction material such as glass, steel, and the likefi'fgdesired. Below the eye in each arm there'n'iaybe a hole or opening 25, and the vertical, edges of each arm' are chamfered, as

shown at 26, the sharp edges being next to the inner edge of the cap 8. The chamfered.

edges '26fact with the adjacent corners or edges of the notches 16 to cut out the waste as it accumulates or to prevent it from accumulating at these points and to maintain the surroundingportions of the apparatus in'a condition free from lint and dirt, the loosened matter being thrown out by the'rapidly re} volving arms and blown away by the draft producedbv the rapidly revolving spindle and bobbin. Furthermore, the sharp edges ofthe arms offer less resistanceto, the air than would dull edges and cleave their Way through-the air, as it were, more easily.

The openings 18, 19 and 20in the guide and its arms not only lighten the'structure, but afford passages for. the currents ofair created by the spindle and bobbin when in motion, to the-.end that the motion ofthe guide is effected in part by the whirling air, j and besides all dust and dirt are expelled by the draft'through such openings so that the yarn or thread is kept clean. The dust and length;

Another. importantand valuable feature is found in theplurality of guidehooks Whereby it isunn'ecessar-y when the yarn or thread breaks, to rotate. the guide in order to bring anattaching point in front of the operator, because there is always such apoint in the form of one of the arms 21 in thatposition, consequently the reengagementof the yarn or thread with'the guideiseasilyand quiekly 5, brought about. I One or-more devices that I term cleaners there being usually three or four such devices Eachzcleaner comprises a; base block 27 ad-- justably arranged on the cap 8, and the vertical, revoluble, denti form roller. or" cleaner proper 9- mounted on said block. In the 1 present case each block 27, which .lies horizontally on the cap, has a longitudinal slot 28 therein througli which a screw-29 passes into threaded enga ement with said cap to retain. 9 said block n place, and the roller 9 is mounted on a spindle 3.0, rising fromthe block near the front end thereof. Upon loosening. the-" 00 screws 29 tl'i'eblocks27 with their rollers 9 can be adjusted to bring said rollers nearer to 5 the path describedby the guide arms 21 or to move them fu'rthera'way fromjsuch path, as i the size and quality of the yarn" or thread may will be clear to those skilled inthe art,\hence it need not be set forthherein at further.

. -.120 The construction ofthe apparatus issuch that'the adjustmei' t of the ball-bearings can be made with great. nicety and all Wear there. of" taken up; moreover, the. assembling and separating of the parts is rendered easy and convenient. v

It is obviousthatrnanychanges ofminor importance. can be made-in i rnyfiapparatus;.-

without departing from the nature. of my n vention. I
